5 of 5 UMS4 USB Four-Slot USB Fast Charger November 26, 2022
Reviewer: David St from N  
Provides lots of information on the graphic display:
Present voltage, rate of charge in milliamps, MAh added (amt of gas added to the tank), battery condition (GOOD, POOR, shorted, FULL), internal resistance. Any good quality 5v/2amp USB charging adapter will power it.
